Any advice on switching baby from rice cereal to flavored baby foods such as bananas, apples, carrots, etc. (stage 1) ? Tried that today and my son makes this face like its the most disgusting thing in the world😅 even tried mixing a little flavor in his rice cereal. I know he's not used to it and that they say to try giving it to them at least 10 different times to make sure. Just looking for some tips, thanks.!
